in a. direction, substantiallyvertical. It

would take considerably more power to swing.,r the finger and allow the thread to drop ott were the bearinget 2l not provlded. With the arrangement disclosed, the thread drops olf from the sweep under a light pull.

heter-ring to the iunction of the bearing 2l, should the operator inadvertently thread l the yarn below this bearing instead et above the sweep.

lt will be observed that the sweep swings within the limits of the guard, that is to say. it is guarded throughout its movement. Further. it will be clear that whether the guard be t'ormed ot the sheet metal member and the wire portion, or be otherwise termed, the end of the sweep is guarded in all `positions, the guard presenting un edge directed laterallvand unbroken troni end to end except at un intermediate point where the c revice occurs for the inlet and outlet ot thc thread, this in the particular construction selected to illustrate the fcntl-tres of the invention beingl between the end ot' the/linger lf) and the bearing' nicinber 20, this crevice bein.;y oit n width to permit thremlinn` oi the vorn through it or to permit thedropping through ot the thread when the sweep linger swings down to its low limit. This construction, therefore, with the laterally directed edge ot the guard snbstantially intact from its upper to its lower end, presents no protnberance or ends open which the thread may catch. The end of the finger le is guarded by a portion oJl 20, and any thread engaging the portion 20 would, under the pull thereof, slip oli of the point ot juncture of the portions 20, 2l.

We claiines our invention-4 l. ln combination in a stopV motion tor knitting machines, o guide t'or the thread, a sweepl'inger pivoted to swing' in e plane inclined down 'ardly from its opper position toward the guide, a connection between the sweep linger and guide, a releasing' linger, and a guard arranged in an inclined plane parallel to the plone ot movement ol the sweep, seid sweep moving substantially within the limits of the guard from its thread holding to its thread releasing,r position, substantially as described.
